To all whom t may concern:

Be it known that I, CHARLES I-I. MYERS, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Lamp, of which the following is a specilication.

The invention relates to a lamp or candle.

The object of the present invention 'is to improve the construction of artificial candles and lamps, and to provide a simple, inexpensive and eflicient one of increased brilliancy, adapted to burn for a considerable length of time, and capable of being readily refilled.

With these and other objects in View, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, propo-rtion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing' any of the advantages of the invention.

In the drawings -Figure l is a perspective view of an artificial candle, constructed in accordance with this invention. Fig. 2 is a central longitudinal sectional view of the same. Fig. 3 is a transverse sectional view. Fig. 4 is an elevation partly in section, illustrating the construction of the removable wick member. Fig. 5 is a central vertical sectional view of a lamp, constructed in accordance with this invention. Fig. 6 is a horizontal sectional view on the line 6 6 of Fig. 5.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the embodiment of the invention illustrated in Figs. 1 to 4 inclusive of the drawings, is illustrated an artificial candle, provided with a cylindrical outer casing 1, designed to be constructed of metal, or other suitable material and to be enameled or otherwise coated or finished to presentvthe appearance of a plain or ornamental candle. The casing 1 has a flat bottom 2, provided with a vertical annular flange 3, suitably secured to the lower end of the cylindrical portion of the casing, preferably by being soldered or brazed to the inner face of the same. The flat bottom is equipped with an elastic plug 4 of rubber, or other suitable l material secured to the bottom by a screw 5, or other suitable fastening device and adapted to fit in a socket 6 of a candelabrum or the like, as illustrated in dotted lines in Fig. 2 of the drawings. The candle is designed for Candelabra, alter and various other uses, and the screw 5 pierces the bottom 2 of the casing and is embedded in the tapering plug 4. The upper end of the plug 4 is of less diameter than the lower end of the casing', which projects beyond the sides of the plug to form a stop for engaging the top of the socket 6, as clearly shown in Fig. 2 of the drawings, to prevent the device from being inserted too far into the said socket. Various other means, however, may be employed for enabling the candle to be detachably mounted in position, and it may also be applied to a permanent support (not shown) when desired. The outer cylindrical casing' is provided with a reduced upper end 7, and it has a tapered portion 8 located immediatelv below the cylindrical end and forming an exterior bevel, and adapted to enable the candle to present an appearance similar to an ordinary candle. Within the casing 1 is arranged a perforated tube 9, forming an inner wall and spaced from the outer casing to provide an intervening space for the reception of a pluralitv of wicks 10, but other absorbent material may be emplo-yed if desired. The lower end of the perforated tube is suitably secured to the bottom 2, and its upper end 11 is flared and is suitably attached to the interior of the outer casing 1 at the reduced upper terminal portion 7 thereof, as clearly shown in Fig. 2 of the drawings. The flared upper end of the perforated tube facilitates the introduction of a removable wick member into the body of the candle. The removable wick member is provided with an outer felt sleeve 12, arranged around or upon a tubular frame 13 of woven wire, or other suitable material. The tubular support or frame 13 receives a relatively loose wick 14, constructed of wicking and adapted to freely convey a hydrocarbon or other burning fluid to the top of the candle. The inner tubular support, which surrounds the wick, prevents the latter from being unduly compressed and also enables the wick proper to be readily renewed when necessary. The upper portion of the inner tubular support is arranged on and is preferably secured to a short centrally arranged metallic tube 15 of a cap 1G. The cap 16, which fits over the upper end of the body of the candle, is provided with an eXteriorly threaded flange 17, which engages interior screw threads of the upper' reduced terminal portion 7 of the outer casing 1, as clearly shown in Fig. 2 of the drawings. The centrally arranged metallic tube 15 pierces the cap and projects above and below the same, and its upper portion 18 is exteriorly threaded and receives an adjustable sleeve 19, adapted to be raised or lowered to extend the tube along the wick. The extensible sleeve 19A is provided with a milled rib 2OVV to enable it to be readily adjusted on the threaded upper portion of the central tube of the cap. The wick member is removable for supplying the candle with a quantity of burning fluid, and the perforated chamber formed by the fixed foraminous tube 9 is filled half full of fluid to be consumed in the candle. The wick member is then replaced and as it is slowly forced into position. the liquid will saturate the outer absorbent wicks, the inner absorbent sleeve of felt and the central wick, which will feed the fluid to its upper end. the candle is first lighted, it will burn a flame similar to an ordinary candle or lamp. The adjustable sleeve is gradually raised until the candle burns without smoking, and as the sleeve becomes heated the hydrocarbon liquid will be vaporized and the candle will burn with great brilliancy. The arrangement of the absorbent materials er1- ables the more or less highly volatilized hydrocarbons to be burned with perfect safety. The wicks, which are arranged in the annular space, are cylindrical, as clearly shown in Fig. 3, and the number may be varied with the size of the candle.

In Figs. 5 and 6 is illustrated another form of lighting device in which the candle heretofore described is embodied in a lamp structure. The lamp, which is provided with a suitable base 21, has a reservoir or font 22 supported by the base and consti-Y tuting a portion of the outer casing, which has an upper cylindrical extension 23 corresponding to the outer cylindrical casing of the candle. The cylindrical extension or upper section o-f the outer casing is provided with a reduced cylindrical portion 24, and it has an intermediate tapered portion 25. The reduced terminal portion 24 is interiorly threaded to receive an eXteriorly threaded flange 26 of a cap 27, provided with a central metallic tube 28, piercing the cap and extending above and below the same and having an exteriorly threaded upper portion 29. Within the outer casing of the lamp is arranged a perforated tube 30, forming an inner perforated chamber and spaced from the outer casing and sur-l rounded by a series of cylindrical wicks 31, The cylindrical wicks, .whichA surround the When i fixed perforate tube, are constructed and arranged similar to the wicks 10 of the candle, and the space within the font or reservoir exterior-ly of the wicks is filled with wool 32, or other absorbent material. The font or reservoir is adapted to contain an increased amount of burning fluid, and for this reason will burn for a much longer period than a candle, which has only a limited capacity. The upper end 33 of the perforated tube is flared similar to the perforated tube 9 of the candle, and it is suitably secured to the outer casing at the inner end of the reduced cylindrical portion 24.

The perforated tube 30 of the lamp receives a removable wick member, con-` structed similar to that of the candle and comprising an outer absorbent sleeve 34:, a woven wire frame or tubular support 3,5 to receive a wick 36 and the said cap 27. The upper threaded portion 2,9 of the tube of the cap, however, is not equipped with an adjustable sleeve, but is designed to re-v ceive a burner of any suitable character'. A plain burner may be used, but as the burning fluid will be vaporized by the heat of the burner, the lamp may be equipped with an incandescent mantle if desired.

In each form of the invention, the burning fluid saturates the absorbent material and is contained within the same, but is Vfed as required to the central wick, which will burn until the interior of the lamp is idry. The perforated tube of the body of the lamp or candle and the woven wire tube or tubular support of the removable wick member permit the liquid to pass readily through their openings.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A lighting device of the class described including an outer casing, an inner perfo.-` rated wall arranged in spaced relation with `the casing, outer absorbent material surrounding the perforated wall and arranged in the said space, and an inner removable wick member comprising a tubular support, an outer absorbent sleeve arranged on the l tubular support, and an inner wick extendl ing loosely through the tubular support and removable therefrom and relieved of pres- -sure by the same, the said support being a removable wick member insertible through the flared end of the perforated tube and comprising an outer absorbent sleeve, an

inner tubular support, and a Wick loosely arranged Within the tubular support, the latter being provided With openings for the passage of a liquid.
